PostScript Type 1 fonts end of support

Adobe will disable support for authoring with Type 1 fonts in January 2023

Overview

Type 1 fonts (also known as PostScript, PS1, T1, Adobe Type 1, Multiple Master, or MM) are a deprecated format within the font industry, replaced by the larger glyph sets and more robust technical possibilities of OpenType format fonts.

Type 1 fonts were introduced by Adobe in 1984 for use with its PostScript page description language, and became widely used with the spread of desktop publishing software and printers that could use PostScript. In 1996, Adobe products and type development began to concentrate on the use of more versatile OpenType fonts rather than Type 1.

While the use of Type 1 fonts is still supported by some operating systems, it is not supported in many environments crucial to modern platforms, including web browsers and mobile OSes. The lack of support for Unicode information in Type 1 fonts also limits their ability to support extended language character sets.

Users will no longer have the ability to author content using Type 1 fonts beginning January 2023. Until that time, users will be able to work with their Type1 fonts without any change.

Some products, including Document Cloud applications, will continue to display and work with Type 1 fonts as they have all along.

Note:

Photoshop will end support for Type 1 fonts in 2021, as announced in 2019. See the Photoshop announcement for more information.

Adobe applications will not recognize the presence of Type 1 fonts, even if you have Type 1 fonts installed in your desktop operating system:

1. Type1 fonts will not appear in the Fonts menu.

2. There would be no way to use previously installed Type1 fonts.

3. Existing Type1 fonts will appear as “Missing fonts” in the document.

Type 1 data embedded in file types such as EPS and PDF will be unaffected by this change, as long as they are placed for display or printing as graphic elements. If those files are opened for editing in applications such as Illustrator or Photoshop, they will trigger a “Missing fonts” error.

Many fonts published by Adobe Type in the past (such as Adobe Originals) are available from the Adobe Fonts service for free with your Creative Cloud subscription. Perpetual licenses for these and other OpenType format fonts published by Adobe are available for purchase from our partner Fontspring.

Users who purchased Type 1 fonts not owned by Adobe should contact the font foundry that published the font(s) to learn whether an upgrade path to the OpenType format is available.

Converting Type 1 fonts to the OpenType format is possible but will produce a sub-optimal result. Additionally, converting your files may be prohibited by the font foundry’s End User License Agreement. Please consult the license agreement or contact the foundry directly for more information.
